Update target button is disabled after schema comp

Question

I have created database project using VS 2012. Once the schema comparison is done, the update target button should be enabled to sync with target.

But it's not getting enabled. Any help plz.

I'm using VS 2012 with sp 3, SQL Server 2012,

Answer 1

Workaround:

In my case. Fixing Error was not priority task. Also i was not able to find any Error in Error List.

Its just you dont have to use your "Visual Studio Database Project" in source or target. Instead of using project, create a temp DataBase using script already with you.

Select this (or these) temp database(s) in source and (or) other in target.

Button must be Enabled.

For me getting difference was far more important than fixing the issue. Hope it helps you. With some more improvisation.

Answer 2

Check in Error List if you have any error, I have a non recognized word in VS (but it does in SQL Server), I commented it out, re-compared and it was enabled successfully.

Answer 3

the everytime you open the "options" on "schema comparison" you must click on "compare" button again to activate the "update" button. However if it doesn't work at the first time, just close and reopen the Schema comparison file again.

Answer 4

And after all, when you have the available Update Target button and the disabled Generate Script button.

See if your source is a database and your target is your SSDT project.

If so then click "Switch source and target" button.

The Generate Script button will become available.
I.e. a SSDT project must be the source and a database must be the target in the Schema Compare window.
